go call you physician or dentist and ask for a prescription of benadryl, mAA
lox, and lidocaine. It is commonly known as the "magic mouthwash" and I used to prescribe it all the time for patients going through chemo or had systemic diseases that created chronic apthous ulcers (aka canker sores.) If for some reason you can't get to the dr., use the combination of equal parts liquid benadryl and mAA
lox (or mylanta) gargle and swish for 60 seconds then spit..
